I'm glad I wasn't watching today when it dipped down. I was watching level 2 early this morning and noticed a couple of large lots being sold. My guess is that Micro-Fluidic Systems needed more cash to get things rolling. They got 2,375,000 shares and could have been trying to sell some. Also, some investors may be panicking about a possible de-listing from NASDAQ, but I'm holding even if it goes to a lower exchange. The bio-threat devise is going to be very valuable and news-worthy with all the crazy people, floods, earthquakes and other disasters that don't seem to quit. Also, the devise that checks for blood sugar by analyzing the breath will be a revolutionary product if it's completed as planned. I hope the stock rebounds tomorrow!
